Upon weathering the Canada Hill granite takes on a dull gray appearance with quartz and garnet becoming prominent due to their resistance (Berkey and Rice, 1921). Canada Hill granite has been dated by Potassium-Argon dating to between 800-900 million years old by the Lamont-Doherty Earth Observatory of Columbia University (Schuberth, 1968).

Abstract Harvard University

The calcite coexisting with apatite in phosphatic rocks is similar in both δ 18 O and δ 13 C to the structural carbonate of the apatite. Even though phosphate may exchange its oxygen with environmental water to a greater extent than we originally claimed ( KOLODNYet al., 1983), it is probably still a very good isotopic recorder of sedimentary
